mg, sawing, and the like marble, anite, stonefmetals, glass, and in general a matev rials capable being worked.

The machine comprises three tool-holders, to each of which can be attached either a shaping or turning grinder, or a polishinghead, or a drill,'or a saw, or any other suitable tool, and allows 'to be carriedout on the blocks of material of an kind that are to be worked all operations w 'ch may be desired. The three tools are arranged one upona vertal axes tical axis and the two others on two horizonplaced at right angles. They can work horizontally, longitudinally, and transversely.

3 The following movements can be im arted to the carria e of the machine on w 'ch fixed the bloc to be worked:

- lableby hand.

First, an'automatic longitudinal to-andfro movement, this motion also being. regu- Second, a progressive motion of trans-;

verse displacement of the carria e.

Third, a progressive motion 0 vertical placement of the carriage. These two last displacements can be controlled either automatically by the longitudinal to-and-fi'o motion of the'carriage after each passage of this latter beforethe. tool or manually by means of a lever.

engagpd upon the screw f which then drives thls s de lon 'tudinally. 9 On the sli e E, Fig. 4, is transversely adjusted by dovetailing a second slide H, which can be moved on the'slide E by means of a screw it, mounted in'the latter and on which is movable a nut 7)., driving the slide H tralnfi- 9 e screw it is automatically driven by a fork k mounted'loosely at its upper extremity. At its lower part this fork 1s provided with an arm h, which at each longitudinal to-and-fro 1 movement of the carriage alternately comes in contact with the fingers h and h", the position of which is adjustable upon the carnage. The contact with these fingers causes the fork h to oscillate alternately at the end of each stroke of the carriage infront of the working tool. These oscillations are transmitted to the screw h-by two pawls h andh", mounted ing a mechanism G similar tothatof ordin lat es with back gear rg.j A movable h ,-nut e, secured to the s'hde E, can be loosely on a pivot in the upper portion of the fork h These pawls, which act in opposite directions, are respectively in ear with the ratchet-wheels h and b the st of which, 71., is keyed to the end of the screw h, to which it transmits directly-the action of the pawl h, while the ratchet-wheel h is loose on the screw h, which it, drives by means of. its internal-toothed crown h, in gear with a pinion h, revolubly mounted onthe slide E, itself in gear with another pinion h, keyed to the -screw it, and which thus transmits to this latter the action of the. pawl h iiithe same direction as that of the pawl 72]. For working by hand a lever is fixed on the square h at p the end of the screw, care being takento reverse the paw-ls h and it", so that they are no longer in gear with the ratchets. In the same way thereis mounted on the slide H, on a circular dovetailing, a third slide I, 'Figs. 2 and 4, which can be operated by means of a screw 'i, on which moves a nut t, of which the gudgeon t engaged in a slotted" recess i moves the slide I around its axis t, journaled on the slide H. The upper slide I has three T-slots P, which serve for fixing the work, the head and tail -stock of the horizontal lathe, the ellipticalla the, Y &c.

To the carriage is imparted alo'ngitudinal reciprocating motion upon the table F in the ordinary manner. The screw f receives,

dle. may be placed. The carriage thus freed from the driving mechanism can be displaced by means of a handleattached to the end of the. shaft Z and by means of gear-wheels Z, Z [and I, this lastbeing in gear with a longitudinal rack L, secured to'the table F, Figs. 1 and 2. L

Thetable F and the whole of the slides E, H, and I, which form the carria e proper,

being movable upon the said tab e, can be displaced around trunnions J 'J, Fig. 4. I When 1t is desired to saw a block at any particular angle, the inclination'of the Whole apparatus is obtainedb means of a shaft K, one of the ends of whic has-a square on which can be secured a handle. This shaft is journaled in supports forming part ofthe table-F, carries two worms 7c, engaging two worm-wheels respectively secured to a nut k mounted in a fixed support it secured to the table F andable to move upon a screw 7:, jointed at 7'1 .upon a die 1c, movable in the guide k of a fixed support 76?, forming part of the fixed portion at the base of the trunnion-J. The carriage E H I, table F, and all the controlling andreversing mechanism is supported by the trunmons J J and can receive an upward or a downward movement.

Each of the trunnionsJ J is attached to a I I piston M, seated in a column forming a cylinder N. The lower part of the piston M forms a nut in which is engaged a screw 71., on which bevel-wheels are engaged by a third bevelwheel 0 secured to a toothed wheel 0", having a bearing in a support 0 The toothed wheel 0 is itself in gear with another gear 0 keyed on the shaft 0 each end of which carries a bevel-wheel 0 gearing with the bevelwheels n", keyed to the base of the screws n, supported by sockets n in the lower portion of the columns N. The lever 0 carries at its lower end a transverse arm 0 in the path of which are arranged two fingers P P, the position of which is adjustablein a guide 1) of the carriage, which during the to-and-ffo motion of the latter reverses alternately to Y right andleft the lever 0, which in its'turn acts sometimes on the ratchet 0 and at other times on the ratchet 0 and causes, both on mechanism carried by the; pistons M M to rise automatically. Of course the rising and falling motions of this mechanism can be obtained by hand for instance, by means of a handle to be fixed on the square at the end of the shaft 0 and by engaging or disengaging the pawls 0 and o from the ratchets o and 0 In order to turn a column so as to form thereon flutings, &c., there may be arranged onthe carriage a'puppet Q and a tail-stock Q, Fig. 5, this lathe being driven in any suitable manner. For turning or molding ovalshaped ieces' we set upon the carriage an eHipticaFlathe constructed in the following manner :On a pedestal R is adjusted by dovetailing a movable slide S, and this slide is provided at its upper part with a circular rabbet 8. Its position on the pedestal can be varied by means of a screw 8, secured to the forward and return strokes, the whole I the slide S and able to move along a screw 8 supported on the pedestal R, and which can be operated by means. of a handle engaged upon its. endrs A pointer or index attached to this slide moves in front of a graduated scale on the pedestal. On the circular or tion 8 ofthe slide S is arranged another s ide T, surrounding the circular portion 8 on two sides t t. This slide is furnished with a groove t, formed from one of the sides t to the other, and a slot t formed at the bottom of the slot t, crosses the slide from one side to the other. The slide S also bears a slot 3, crossing it from one side to the other. An axis U, suitably guided in the pedestal R, passes through the slides S and T and is ended by a rectangular head it, adjusted to slide in the slot t of the slide T. Toward the base of the axis U is fixed a worm-wheel u, in gear with a Worm a keyed to an axle 'uP, at the end of which may be attached a handle.

When the axis of the circular part of the slide S is coincident with the axis U, the slide the parts which support this slide are revo' luble in a circle, When the axis of the slide S is removed from that of axis U, the slide T, driven in a circle by the head 'w-being constrained by its edges t t to follow the circular rabbet s s of the slide S eccentric relatively to that of the axis U, turns in an oval manner? following the circular rabbet s, the slide T being displaced and held by the head at of the axle U. This latter is impressed with a circular' motion, regulated'by hand by means of a handle through theaxis 41 of the worm a and the worm-wheel a. For turning 0r shaping an oval piece of work it is sufiicient to displace the axis of the slide S with regard to the driving-axle U by an amount equal to the difierence between half the major axis and half the minor axis of the ellipse X, this distance being read on the graduated scale marked on the pedestal R "and indicated by the pointer carriedby the slide S. This distance being fixed, the point of contact Y of this ellipse with the grinding-tool Z remains constant.

It will be understood from the above description that blocks placed on the carriage can easily be displaced longitudinally or transversely or be displaced angularly'in the horizontal and vertical planes and, lastly, be

raised and loweredthat is to say, they can be easily displaced in all directions. This the combination of a slipport A rovided with several tool-carriers mounte at right angles one to the other, a table F on which moves the carriage I, H, E comprising a plate I on which is secured the material to be operated on, a slide H under the said plate to move it in a circular direction in a horizontal plane around a central vertical axis it, a second slide Eunder the first slide H to move the said plate Itransversely ,the said table being mounted on a horizontal axis to be moved in a vertical plane, and standards M supporting said horizontal axis'for adjusting the height of the table.

2. In a machine of the character described, the combination of a table. F, a plate I, to carrythe material to be operated on, a means i, 01, i i under the said plate-to move it by hand in a horizontal plane around'a central axis '5', a means it h to -move automatically and progressively the said plate longitudinally in a continuous and intermittent way in one direction and in the other, ameanskk to move the table by hand around ahorizontal axis, and a means 0 0", n, n to raise and lower the said table automatically and rogressively and asupport A carrying severa tool-holders B, a means (1 d to cause the said tool-holders to rise or descend by hand, and a separate control for each of the tools.

In testimony whereof we have signed our names to this specification in the presence of two SllbSOIIblIlg witnesses.
